[PATCH v7 00/16] mtd: nand: denali: Denali NAND IP improvements

This patch series intends to solve various problems.

[1] The driver just retrieves the OOB area as-is
    whereas the controller uses syndrome page layout.
[2] ONFi devices are not working
[3] It can not read Bad Block Marker

Outstanding changes are:
 - Fix raw/oob callbacks for syndrome page layout
 - Implement setup_data_interface() callback
 - Fix/implement more commands for ONFi devices
 - Allow to skip the driver internal bounce buffer
 - Support PIO in case DMA is not supported
 - Switch from ->cmdfunc over to ->cmd_ctrl

18 patches were merged by v2.
11 patches were merged by v3.

5 patches were merged by v5.
